Si,

I still want to see your shopping list for all of the parts.  What transmitter do you use with that tiny receiver?

I was thinking of picking up one of the small R/C tanks that come with two speeds for about $12 to install in my new railbus that I'm starting to work on.

That'll work for me.  Wonder if I can make the canon really fire.

Hi Michael :wave:



When I decided to have a go at R.C. I wanted to find an economical & workable solution.

I thought that a 'decent' workable solution, might be possible for about £15.

This was when I was still looking at a certain type of car/transmitter, to use for parts.



Having made the decision to go for a 'modular' system, rather than 'on one board', I needed a cheap transmitter.

I actually bought a 2.4GHz transmitter recently, for £0.99p + £3.45p P&P.

I could not resist it at the price, as it also looked simple & ideal for 'customization'.

Whether it will work with the receiver I have ordered, is as yet unknown.

Also, for most people, the option of picking up a transmitter for this price, is pretty minimal.



In deciding not to go for the initial 'cheap car' option, my budget 'realistically' possibly went up by about £10.

If the transmitter I have works OK, then I am 'on budget' to do the lot for £15.

If the transmitter I have doesn't work OK, then I will need to get the 'FlySky' transmitter.

This means my budget will increase, to an 'all in' price of around £25.



The setup will still be 'modular', so any toasted-parts can be easily & cheaply replaced.

Also the 'availability' of parts is important as well.

The 'FlySky' TX. & Rx. is not only very cheap at less than £20 inc. P&P, but very widely available.



I thought I would slowly but surely, document my 'economy system' for those who may be interested.

One thing I aint, is QUICK !

Spare time, other models to be made etc. etc. means this isn't 'a race' for me.

I would just like to come to the cheapest & highest-quality solution that I can reasonably find.



£15 or perhaps more realistically £25 spent, is an encouragement to those who might not want to spend 'the big bucks'.

Since I am still waiting for many parts to arrive, it is obviously hard to recommend anything.

Although what I have speced. is not 'rocket science' & is essentially tried & tested R.C. practice.



The bottom-line for this project, will however, always be quality AND cost !

Moose Mountain money, goes on modeling materials, NOT microchips !! ;)



:moose:



Si.



This is the transmitter that 'went for a song'. ;)

I have it here & have had a good 'nose around' inside it ! :shocked:





This is the 2.4 GHz 'FlySky' frequency-hopping transmitter & receiver twin-set, available for $20 inc. P&P on eBay.

Nice summation, but I think you forgot to take into account that for that receiver you need an additional 5V-supply or BEC, as it needs at least 4.8V, not exceeding 6V ( This is the standard R/C spec. ). Normally the speed-controller's logic takes its supply from the receiver, so that BEC must be able to supply both. Not a great issue, but to be kept in mind.
When I was still in 1:20 Outdoor Railroading, all my BPRC locos were equipped with components similar to Si's listings. You just have the room there for all that modularity, which I doubt will be available in 1:35.
May I also humbly remark that for RR puroses, those car transmitters are almost unusable in their 'as-is' form? The trigger-type speed control doesn't work so well with locos, when you want some more than on-off operation. Forward and reverse swings are different and do not give the same speed range. The spring-loaded centered steering wheel is a wee bit better, but still you have only some 30..45° degrees of control adjustment.

Hi Helmut :wave:



The 5 Volt logic-supply, is made by the E.S.C.s that I have speced.



So ... inside the loco, there needs to be :-

Receiver.

Electronic Speed Controller.

Battery.

DC-DC 9 Volt step-up regulator.



The parts should easily fit in the 1:35n2 Plymouth ... I think.

The R.C.ing business is generally a 'shoehorning' operation, I have noticed.

Unless of course you are doing perhaps 'O' or 'G' standard-gauge, or have huge tenders etc.



I have both a 'fixed' & 'adjustable' DC-DC step-up regulator coming.

Both extremely small.

More on these soon.

One cost £0.57p inc. P&P

The other £1.28 inc. P&P



:moose:

Hi again Helmut :wave:



Sounds like I might as well just give up then ...

... and simply go back to using my reliable, cheap & easy to wire-up, Tri-ang resistance-controller.



Maybe I should get out, while the going is good ...

... I've only wasted £15 so far.

Perhaps I could sell the parts on eBay & not loose too much money ?



:f:



Si.

Gee, I didn't know that the "r/c car" pistol transmitters don't control locos properly. I guess that I will need to get rid of the two I have been using for 15 years or so and find something "more appropriate". I have believed that they worked pretty well all this time but what do I know anyway?
Hmmm, since I am on social security, I imagine that I will have to keep things as is and have fun running my antique trains with my caveman equipment.
Now, is anyone willing to front me the money to buy the latest toys?

This is why I ask the experts to save myself a lot of frustration. 

I'll check out the FlySky
